In reply to The_flying_climber: It is quite a round number isn't it? but I've found that most stated weights are within 10% of what my postal scales weigh for outdoorsy clothing. Marmot were very wrong though on one jacket's weight some seasons back - I think often it's just the intern or whoever entering the info on the website who makes a mistake rather than any attempt to pull one over on us! ME had a few that had to be those sort of mistakes on their sleeping bag website when they updated it this year.

500 gr is also not super light by modern standards, but I think there are disadvantages in super light jackets for hard mountain use anyway.

I just put my Roc Blanc on my analog kitchen scale. The scale isn´t exact but it weighed about 400 grams.
I had my jacket for about 2 years and I love it. I use it mainly for for ice climbing in Sweden and Norway.
And no, I have nothing to do with Tierra.
